"Wow." Oliver sucked a cold breath. It didn't take too long for him to realize that this was the ghost that had always been with Haruka.

It seemed that she could become an exorcist, but her essence was still supplied by Haruka.

When she released that water talisman, all the gushing water pushed back all the zombies that tried to climb it, causing them to enter the building and use the stairs instead.

Oliver knew that they couldn't stay here much longer, but he was still a bit too fixated on Haruka's action.
